My wife and I started a server together and we have a 1946 days world with caves. Everything was still fine last night after the new patch updated. However, after I spent 1350 spool to get the Tam o Shanter skin today, it shows "Dedicated server failed to start" message when I tried to load the game. I can still create a new world with the same settings with no problem, I just can't load into my old world for some reason. I am using 4 mods (eternal glowcaps n mushlight, lasting endtable decoration, geometric placement, and epic healthbar) but I don't think they caused the problem. I rolled back 5 days, uninstalled all the mods and try again, no luck...I even sold the new Tam o Shanter skin I just bought and see if that's gonna help and still no luck. I tried to deactivate my antivirus and verified integrity of game files in steam and it still doesn't help. I tried to transfer the save files to my wife's computer and open it on her end, the same message shows. Can someone please help me look into it and see what happens coz we spent 1000 hour game time to build this world...Thanks. Attached is the cluster one server log.
Here's the client log. Just in case
